REFINING PULP-ENGINE.

SPEGFCATION forming part of Letters Patent No. 398,845, dated March 5, 1889.

Application filed June '25, 1888. Serial No. 278,079. (No modehl Patented in Canada April 4. 1888, No. 28,797.

To aZZ whom z' may concern:

Be it known that I, J OSHUA NORTON, Jr., a resident of Portneuf, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Refining Pulp- Engines; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, it having becn patented 'fn Canada, April 4, 1888, No. 28,797.

The object of this invention is to produce a refining or finishing engine that shall operate continuously upon unfinished material received from a pulp-beating engine and pro duce iiber of the same character as that pro-v duced by the Hollander operated by skilled Workmen.

In general terms, the invention involves a rotating roll bearing fly-bars whose edges are everywhere equally distant from the axis of rotation, a cylindrical case inclosing said roll and provided with an inlet for unnished material and an outlet for the finished ber, a series of bed-plates or knives Xed in said case, with the edges of the individual knives oblique to the cylindrical elements, and means for the vertical adjustment of the roll.

In the drawings, Figure l is a side view of the apparatus, a portion of the case being broken away. Fig. 2 is an end view with the end of the case and external devices removed. Fig. 3 is a plan of the bed-plates or knives. Fig. at is an end view of the same. a partial end view showing the adjustable shaftsupport and the devices by which it is adjusted. Fig. 6 shows sliding packing-box on interior of cylinder-head. Fig. 7 is a hori- Fig. 5 is zontal cross-section of the cylinder-head on line fr of Fig. 6.

Fig. 8 is a vertical crosssection of the cylinder-head on line .e of Fig. G. In the drawings, A is a preferably metallic g cylindrical case provided. with removable heads A and carried upon suitable supports, i,

lllithin the case is a roll, D, mounted upon a vertil cally-adjustable shaft, C, and bearing fiynbars E. Material to be operated at one end of the cylinder, and the iinished liber is discharged through a pipe, J, at the lower side of the opposite end. Both these pipes may be provided with ordinary valves and connections.

The shaft O revolves in bearings L, which slide vertically in guides Y, mounted upon the supports Z, and is driven by the powerpulley H. The bearings L are adjusted simultaneously by means ot' a crank, G, fixed upon a rod, K, mounted in the guides Y. By means of bevel-gears g g the rod K actuates longitudinally-fixed rods K', seated in the guides Y and having their lower threaded ends in engagement, respectively, with the bearings L.

The cylinder-heads A are provided with oblon g slots M, which permit the vertical adjustment of shaft C. Sliding packing-boxes N are attached to shaft O and move in ways O on the interior of the cylinder-heads.

The bed-plates themselves are vertically adj usted in the usual manner by set-screws 71..

In operation the material is forced into the case at I and carried to the bottom by the rotating iiy-bars, where it is acted upon by the oblique knives, which, owing to th is obliquity, have a shearing action and tend to force the material forward toward the opposite end ot the case. Upon leaving the bed-plate it is carried again to the top and thence again to the knives, and so on, until at the end of its spiral course it passes out through the aperture J as finished liber.

It is evident that any mechanic can varythe means for adjusting' the roll vertically, that one or more bed-platcs may be employed, though two only have been shown, and that the principle and operation of this apparatus will .nevertheless remain the same.

'hat I claim is l. The combination, in a refining-engine, oi' a cylinder-roll, a silitablyanounted shaft, Hy bars secured to said roll, with their edges uniformly distant from the rolls axis of rotation, a cylindrical case inclosing said roll with its iyebars, and a series of knives set in the bottom of said case obliquely to the outer edges ot' the tlybars, substantially as set forth.

2. In a refiningengine, the combination of upon is admitted a cylinder-roll, a shaft and means for adjustH to the top of the case through a pipe, I, placed IOO series ofi adjustable knives setin the bottomof said ease`,jsubstantiallyas auditor-'the purl pose set forth.

4. The combination, with the y-bar cylinder, of the shaft C, sliding bearings L, the oase A, inelosing said cylinder and provided with the bed-plates F, having' knives b oblique to the fly-bars, the guides Y, the threaded rods K, engaging the bearings L, and the crank-rod K, Connectedv by' gearing to the rods K', substantially as described.

In testimony whereof I have signed this specification in. the presence of two subscribing Witnesses. p
